I don't drive hard, I try not to go above 3000 rpm, but I need to going up hills, otherwise I'll be going 40 mph on the freeway. This car is a brick. I had a Lexus GS300 before this that got better gas mileage, which according to the EPA, I shouldn't be. Is there anything else I can do to improve my mileage? I have a turbo lite, should I be using regular gas to improve my mileage? Thanks.

Welcome to the Forum, PTCruisin808.

You were wondering about your mileage and stated 220-230 miles to a fillup. You'll have to divide the miles driven by the gallons to find the mileage so we can get a idea.

What was the gap set on your plugs? That could determine good or bad mileage.

The Turbo lite is designed to use regular gas. Most Turbo's that I have seen will have a tag on the gas cover saying to use premium gas IF they are a HO Turbo, if it doesn't you should be using regular as you are just wasting money by using premium.
